I've seen threads on the SMPA60 fatal error, but they were only regarding single player. Sometimes when I play multiplayer, The game closes down and I get GTA IV - FATAL ERROR SMPA60, within the error message, it says: "Unrecoverable fault - please restart the game." I think it's because of people using certain mods in multiplayer (Edited weapons.img, vehicles.img, etc. Is my game crashing because of other people playing with edited .img files (weapons.img, vehicles.img)? Is there a way to prevent the game crashing...?
